JIMENEZ, F. N. et al. Obtaining and characterization of coatings of Brushite, Titanium Dioxide (TiO2) and its bilayers on steel 316L. Entre Ciencia e Ingenieria [online]. 2018, vol.12, n.23, pp.131-139. ISSN 1909-8367.  https://doi.org/10.31908/19098367.3713.

The synthesis and study of biomaterials possessing biomechanical and biocompatibility properties is a subject of continuous research by the scientific community. Compounds such as hydroxyapatite (HA) and brushite, which have interesting properties and are biocompatible, are being used as a barrier layer between materials such as 316L steel and biological media, thus reducing the iron ion flux from the steel to the Biological fluids. Although recent studies have presented advances regarding the adhesion of these materials to different metals, there are still open challenges to improve the adhesion of these materials to the desired metal. In this work, we have implemented coatings composed of brushite and titanium dioxide (TiO2) bilayers. Following are the protocols followed for synthesis of brushite, titanium dioxide and bilayer coatings on 316 L steel, as well as the structural characterization by infra-red spectrometry (FTIR), X-ray diffraction (XRD), electron microscopy of Scanning (SEM) and dispersive energy spectroscopy (EDS) of the coatings obtained.

Keywords : Brushite; Titanium Dioxide; electrochemistry; Silar.
